This old box is based on gopro hero2. The idea was to unbox the gopro, put some hardware sync system, external power up, etc.And the gopro hero3 did came out. Making the whole development useless as arrays of hero3 can be wifi controlled to start / stop.The only advantage of this setup is external battery. Or hero3 cannot work anymore without battery even if pluged into external power source.So we dropped that approach for something more usable without destroying gopro anymore.
